[MapProxy] WMS default version

Tue Jun 23 23:16:29 PDT 2015

Hello Anne,

thanks for your answer. I know, Version 1.3.0. introduced some confusing changes ;-)

Unfortunately I can’t find your statement for VERSION parameter requirement in the WMS specs.

WMS 1.1.1 says:

-          GetCapabilities Operation: VERSION is optional

-          GetMap Operation: VERSION is required

-          “If no version number is specified in the request, the server shall respond with the highest version it understands and label the response accordingly.”
WMS 1.3.0 says:

-          “The VERSION parameter is mandatory in requests other than GetCapabilities.”

-          “In response to a GetCapabilities request (for which the VERSION parameter is optional) that does not specify a version number, the server shall respond with the highest version it supports.”

So in my eyes MapProxy should respond with version 1.3.0 for GetCapabilities requests. For all other requests the VERSION parameter is mandatory.

Kind regards,

Dirk

Hello Dirk,

Newer does not always mean better. But that is probably not the reason for this case.

In WMS specification 1.1.1., the VERSION parameter is optional.
In WMS specification 1.3.0., the VERSION parameter is mandatory.

So, if you do not specify a version, the service should fall back to 1.1.1.

Dear list,

I’ve noticed following behavior in MapProxy: on WMS requests to MapProxy without a VERSION parameter it’s assumed that the default version is 1.1.1. Shouldn’t this be 1.3.0 as this is the highest supported WMS version?

It seems to be a hard coded behavior. It would be nice if this default version could be configured. Are there any plans to make this configurable or increase the default version?

Kind regards,

Dirk Thalheim
